* feat(invoices): implement öresavrundning logic and next invoice number preview - Added `getDisplayTotal` utility to handle rounding for SEK invoices based on company settings. - Updated `InvoicesPage` to utilize the new rounding logic when displaying totals. - Introduced `peek_next_invoice_number` function to allow previewing the next invoice number without consuming the sequence. - Modified invoice number generation to remove the year prefix and prevent truncation of numbers exceeding three digits. - Enhanced tests for invoice number generation and rounding functionality to ensure correctness. - Updated PDF template to reflect new rounding logic for totals and display appropriate values. - Adjusted company switcher to hide options in sandbox mode. - Improved error handling and logging in sandbox seeding process. * fix(skatteverket): remove unused scope labels from SCOPE_LABELS and DEFAULT_SCOPES
